Fluid and electrolyte NCLEX questions

Let’s check some of Smart’n’s fluid and electrolyte practice questions with their answers and rationals:

Question One

A client with an electrolyte imbalance is at risk for fluid imbalance related to increased urine output. Which of the following interventions should the nurse add to this client’s care plan that would be most appropriate?

1. Assess for signs of hyperphosphatemia

2. Weigh the client daily

3. Elevate the client's head on the bed

4. Monitor for worsening abdominal pain

A. Incorrect Answer

Assess for signs of hyperphosphatemia

Rationale: This is not an intervention related to fluid imbalance.

B. Correct Answer

Weigh the client daily

Rationale: A fluid volume deficit develops as a result of decreased fluid volume in the bloodstream. It may be associated with dehydration or other conditions that cause volume loss. The nurse should assess the client's weight on a daily basis to observe for increases or decreases associated with fluid levels in the body.

C. Incorrect Answer

Elevate the client's head on the bed

Rationale: This is not an intervention related to fluid imbalance.

D. Incorrect Answer

Monitor for worsening abdominal pain

Rationale: This is not an intervention related to fluid imbalance and the question makes no mention of the client having abdominal pain.

Question Two

The clinic nurse is assessing a client who performs peritoneal dialysis at home. Does the nurse know which lab value is NOT related to dialysis assessment?

1. GFR

2. BNP

3. Electrolytes

4. BUN/Cr

A. Incorrect Answer

GFR

Rationale: The glomerular filtration rate is monitored to assess the level of filtration of the kidneys, which is an indication of kidney function.

B. Correct Answer

BNP

Rationale: The B-type natriuretic peptide is an indicator of heart failure, not kidney function.

C. Incorrect Answer

Electrolytes

Rationale: Electrolyte levels are monitored as an indication of how well the dialysis is filtering waste products.

D. Incorrect Answer

BUN/Cr

Rationale: The blood urea nitrogen and creatinine levels are monitored as an indication of kidney function.

Question Three

The nurse is caring for a client with celiac disease who has developed hypomagnesemia from malabsorption. Which sign or symptom would the nurse expect to see with this condition?

1. Respiratory depression

2. Twitches and hyperreflexia

3. Cardiac arrest

4. Hypotension

A. Incorrect Answer

Respiratory depression

Rationale: The client with hypomagnesemia would instead display shallow respirations.

B. Correct Answer

Twitches and hyperreflexia

Rationale: Hypomagnesemia occurs when magnesium levels in the blood are lower than normal. The condition develops from such illnesses as malabsorption syndromes, alcoholism, and chronic diarrhea. The client with hypomagnesemia will most likely demonstrate muscle twitches, hyperreflexia, tachycardia, and confusion or irritability.

C. Incorrect Answer

Cardiac arrest

Rationale: While the cardiac status of this type of client must be monitored, the common side effects are tachycardia and hypertension rather than cardiac arrest.

D. Incorrect Answer

Hypotension

Rationale: The client with hypomagnesemia commonly develops hypertension, not hypotension.

Question Four

A nurse is caring for a client with hypokalemia as a result of long-term steroid therapy. Based on this diagnosis, which of the following signs or symptoms would the nurse expect to see?

1. Fatigue and muscle weakness

2. Hypertension

3. Nausea and diarrhea

4. Hypoglycemia

A. Correct Answer

Fatigue and muscle weakness

Rationale: Hypokalemia is a condition of decreased levels of potassium in the bloodstream. This can occur from excessive use of corticosteroids. It can cause such signs or symptoms as fatigue, muscle weakness, and constipation, as well as serious effects, including cardiac changes on the ECG.

B. Incorrect Answer

Hypertension

Rationale: Hypertension is not a symptom of hypokalemia.

C. Incorrect Answer

Nausea and diarrhea

Rationale: Bloating and constipation are symptoms of hypokalemia, but not nausea and diarrhea.

D. Incorrect Answer

Hypoglycemia

Rationale: Hypokalemia does not cause a low blood sugar

Question Five

A nurse is caring for a client who is recovering from surgery. The client has developed a headache, muscle weakness, and mental status changes. The nurse notes that the client’s glucose level is 85 mg/dL (4.7 mmol/L), sodium is 126 mEq/L (126 mmol/L), potassium is 4.8 mEq/L (4.8 mmol/L) and calcium is 8.6 mg/dL (2.15 mmol/L). What intervention is most appropriate for the nurse to perform in this situation?

1. Offer the client a drink containing glucose

2. Administer calcium supplements orally

3. Administer 3% sodium chloride solution

4. Give potassium chloride in 5% dextrose

A. Incorrect Answer

Offer the client a drink containing glucose

Rationale: The client does not have a low blood glucose level.

B. Incorrect Answer

Administer calcium supplements orally

Rationale: The client's calcium level is normal.

C. Correct Answer

Administer 3% sodium chloride solution

Rationale: This client is showing signs of hyponatremia, as well as lab values that reflect a low sodium level. A client with hyponatremia can develop symptoms that include skeletal muscle weakness, headache, confusion, hyperactive bowel sounds, nausea, abdominal cramping, increased urinary output, and dry mucous membranes. The nurse would most likely administer a hypertonic solution that contains extra sodium, such as 3% sodium chloride.

D. Incorrect Answer

Give potassium chloride in 5% dextrose

Rationale: This is a treatment for hypokalemia, not hyponatremia.

Benefits of using fluid and electrolyte NCLEX questions

Using fluid and electrolyte nursing questions can offer several benefits to nursing students or individuals preparing for the NCLEX exam. Here are some of the advantages:

FAQs

1- What is the maximum question on the NCLEX?

The NCLEX-RN and PN exams will present a range of questions to the test-takers, with a minimum of 60 to a maximum of 145. Additionally, both tests will consist of 15 experimental questions that won't be considered for scoring purposes.

2- Is 75 questions on NCLEX good?

Certainly, it is possible to pass the NCLEX-RN by responding to just 75 questions. However, it's important to note that the number of questions answered is not a definitive indication of passing. Nonetheless, in 2023, a positive indicator of passing the NCLEX-RN is when the questions become progressively more challenging until the test concludes.
